Do I have hormone imbalance or pre menopause?

I am 34 years old and I have experienced changes in my body since my 2nd child was born, almost 18 months ago. I now have extremelyy dry eyes and I am losing my hair. I was referred to an endocrinologist (per my request) and was told to "take a vacation". Apparently stress is the cause. I am also having panic attacks. I do have some stress but I believe it is something more. What type of specialist can help me with this? My gyno basically told me I was crazy when I told her that I thought I was in pre menopause. I am now on restasis for my eyes and anxiety meds. I want to be back to normal. Please help!
